I tried a couple of times, and the tops turned to dust. It somewhat worked with stalks, but they were not so couscous like in terms of texture, like shredded cauliflower is, I would say they looked more like bulgur :) Also, I was not really big on flavor, I like them better shredded or shaved in a salad.

Thanks -- I think I'll give it a try using a knife instead of the food processor for the florets and maybe keep them in very small clumps, which already sounds a bit time consuming. But, in the name of experimentation and curiosity, I will soldier on! :-)
